settings. The serial interface mode indicates the physical type of the serial interface

used for the SCOM communication. Available modes are RS232 and RS485. RS232

allows a point-to-point communication, i.e. computer and monitor or monitor and

tation is given only by the physical characteristics of the RS485 bus.
